'VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 237,298, dated February 1, 1881. Application filed September 1, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES A. MARSH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

In the drawings, Figure l is a view, in side elevation, of a vapor-burner constructed according to myinvention. Fig. 2 is a plan view of the device shown in Fig. l, with the perforated burning-chamber removed. Fig. 3 is a View, in side elevationof the perforated burning-chamber. Figntis aview, in longitudinal vertical section, of the device shown in Fig. 1.

A is the feed-pipe, through which is supplied the gasoline or other uid to be vaporized. A is an enlarged annular chamber, which is in effect a part of the feed-pipe A. The enlarged annular chamber A' :is constructed to accommodate and contain the perforated combustion-tap B' in the manner indicated in Figs. .l and 4 of the drawings. The feed-pipe A is turned upward after it passes the annular chamber A', and in its upturned portion is perforated, as represented at a, Fig. 4. This perforation is opened or closed by a needlevalve, a', as shown.- By means of the perforation a communication is established between the feed-pipe A and the perforated burningchamber B' through the tube B, which joins the upturned portion of the feed-pipe A and the burning-chamber B.

It will be observed that the burning-chamber B' is perforated with apertures in close proximity to the upper edge of the annular chamber A', which annular chamber, as will hereinafter appear, is the vaporizing-chamber of my burner. The flames, as the)T escape from the lower series of perforations, b, (see Figs. 1 and 4,) will impinge sufficiently upon the upper edge or rim of the vaporizing-chamber A' to heat the same for its vaporizing purposes. This constitutes one of the leading features of my invention, and by this construction, whereby the flames from the burning-chamber B are made to perform the vaporizin g function, I do away/,as already stated, with the necessity of an independent vaporizing iiarne during the use of the burner.

If it is desired to supplya draft of air upon both the inner and the outer surfaces ofthe annular burning-chamber B', a ventilating opening may be made through the licor B2 of said chamber, which will permit the air to pass up in that direction and produce the e'ect of the Argand lamp. The principal function, however, to be performed by the stem or projection which extends centrally from and below the com min gling-chamber is to perfect vaporization by its heat, because during the operation of the burner this stem or projection becomes intensely heated, and therefore, being brought into close contact with the vapor in the commingling-chamber, and also with the walls of the vaporizing-chamber, its function, as just above speciied, is clearly apparent.

C is an inlet, which may be in the shape of a tube or openin g of any description, into which air passes during the operation of burning to supply a sufficient amount of oxygen in the commingling-chamber B'.

D is a valveplaced in the connecting-tube B. This valve may be of any suitable construction, such as shown in the drawings, or otherwise, and its office is to shut off the supply of vapor from the burningchamber B', and to extinguish its light when the burneris notin use. If this valve D is closed during the operation of the burner the vapor generated will escape through the opening D2 in the pipe B, and will impinge directly down upon the feed-pipe A, and will thus maintain vaporization, and the vapor escaping through the perforation a will continue the flame at the opening D2, and thus Ifaporization Without using the burner B can be continued indefinitely. By this provision the'burner B' can be again relit without the necessity of revaporizin g the contained uid in the feed-pipe A.

E is the drip-cup, into which gasoline will escape if the aperture a be opened by the needle-valve a. This drip-cup is designed for the same purpose that drip-cups ordinarily are in vapor-burners`that is, to act as a prime vaporizer in starting the burner. It is iilledwith lOO gasoline, is lighted, and heats the contained gasoline in the feed-pipe A to the vaporizin gpoint in the usual manner in vapor-burners.

I ll the cup E with asbestus, mineral wool, coarse sand, or any porous or granular nonconnbustible substance. This asbestus, or its equivalent, may be covered with a foraniinated plate. By this means the contained gasoline in the drip-cup E will be made to burn slowly and steadily, without the dangerous flashing up that has heretofore been usual, and with better effect in heating the gasoline in the feed-pipe A to its vaporizing degree.

I have herein described the eomminglingchamber as annular orring-shaped. Instead of being strictly annular, however, it may be square, octangular, or otherwise shaped without any departure from my invention, and in using the term annular 77in the specification and claims of this patent I wish this explanation to be noted.

What I claim is- 1. In a vapor-burner, an annular commingling-chamber having a central downwardlyprojecting heater-extension, in combination with a vaporizing-chamber arranged around said heater, substantially as and for the purposes shown.

2. In a vapor-burner, a drip-cup7 E, containing' asbestus7 mineral wool, coarse sand, or equivalent porous non-combustible substance, in combination with a vnon-combustible foraminated covering, substantially as and for the purposes shown.

3. The combination of the combined feedpipe and vaporizing-cbamber A, valve D,per forations a, needle-valve a', and inlet C, substantially as and for the purposes shown.

In testimony whereof I have signed my name to this specication in the presence of 4o two subscribing witnesses.
